7 Claims.

Myinvention relates to portable stoves of a variety adapted to burnliquid fuel, and has for its primary object the provision of a stove inwhich the burner assembly is enclosed within the housing during theoperation of the stove, While the fuel tankis positioned outside of andunder .neath .the housing, with means projecting out of said housing forcontrolling the flow of fuel to the burners in the stove assembly.

Another and further object of my invention is the provisionof a portablestove having a fuel burner assembly and fuel tank connected together insuch manner that the burner assembly can be placed inside of the housingduring the operation of the stove, and for convenient transporting ofthe unit both the burner assembly and fuel tank can be placed in thehousing, thus providing an exceedingly compact stove which takes up verylittle room and can be conveniently packed or carried in an automobileor the like, for camping purposes.

Another and further object of my invention is the provision of aportable stove of the character described in which operating means forthe burners are provided which extend through the housing to the outersides thereof and are advjustable to varying positions to control theamount of fuel flowing to the burners, thereby controlling the flameproducedrby the burners through the combustion of the fuel.

Another and further object of my invention is the provision of a campstove of the portable variety which is exceedingly cheap to manufacture,which comprises few working parts, is simple in construction, and can beeasily and quickly unpacked and placed in operable position for use withthe burners, and also repacked in the housing for purposes oftransportation. 7

These and other objects of my invention will be more fully and betterunderstood by reference to the accompanying drawings, and in whichFigure l is a side view, partially in elevation and partiallylinsection, showing the stove in operating position; 7

Figure 2 is a top plan View of the stove shown in Figure 1;

Figure 3 is a transverse sectional View on line 3-3 of Figure 1;

Figure 4 is a plan sectional view showing the burner and tank assemblyin packed relation in the housing; and

Figure 5 is an end elevational view of the stove as shown in Figure 4.

Referring now specifically to the drawings, and in which like referencecharacters refer to like parts throughout, a housing I is shown,preferably rectangular in shapeand having the usual bottom, sides andend portions, with an open top and a cover I I therefor which is hingedto the housing. In and which in the open position, particularly as shownin Figure 5, is held in practically vertical position, serving toprotect the burners from the action of the wind when using the stove outof doors. An opening I2 is provided in the end wall of the housing l0and a grid I3 is provided which is hinged at one of its sides to therear wall of 'the housing II as shown particularly in Figure 2. Thisgrid extends across the top of the housing Ill and is supported at itsopposite side by the front side wall of the housing II]. A pair ofU-shaped legs l4, i4 is provided which extend through slotted openingsin the bottom of the housing l0 and have angularly disposed ends whichare adapted to be received in openings formed in the front and rearwalls of the housingl0 when the stove is set up in operative position asshown in Figure 1. Extending longitudinally of the housing I0 andsecured to the bottom thereof is a track l generally U-shaped in crosssection and having a stop 7 at the end thereof for purposes hereinafterdescribed.

The burner assembly comprises a cooperating track member H which isU-shaped in cross section and slightly less in width than the track 15located in the housing 19, and is adapted to fit into the track I5 whenthe stove is in assembled operative position. The track I? has a fueltank l8 connected thereto by means of a member H], the ends of whichextend around the sides of the fuel tank H3 at the end thereof, and arespot welded or otherwise secured to the fuel tank l8, this member alsobeing spot welded or otherwise secured to the track member IT. The tankI8 has an opening in the end thereof within which a threaded nut isprovided having a cylinder therein on the outer end of which a gland 2|is provided within which a piston 22 is mounted which provides means forpumping air into the fuel tank I8.

The fuel supply means comprises a manifold 23 having burner tubes 24 and25 projecting therefrom on the upper portions of which burners 26 and26a are positioned in the usual manner.

The burner tube '24 has appropriate fastening I means, such as studs 2?,21, by means of which the burner assembly proper is secured to the trackIT. The manifold 23 has a generator tube 28 connected thereto with avalve body 29 on the outer end thereof, with suitable valves 30 and 3!being provided, this structure being substantially like that describedand claimed in Patent No. 1,914,393 of June 20, 1933. A nipple 32 isprovided which connects the valve body 29 with the pipe 33 connectingthe valve with the fuel tank H8. The manifold 23 has openings in eachside thereof between spaced trunnions, over which a cap 34 is securedand through which additional air passes into the manifold 23 forcombustion purposes. a

The burner tube 25 extends upward, with a vertical passage thereinwithin which a Valve stem 35 is positioned. On the upper end of thevalve stem 35 a valve 36 is provided and on the lower end a link 3'! issecured having an opening therein through which the valve stem 35extends,

with a channel 38 in the valve stem. The link 31 7 is secured to a plate39 which is pivotally mounted on the side of the burner tube 25 by meansof a screw 46, having a spring 4i mounted thereon and adapted tonormally exert its pressure inwardly against the plate 39. The plate 39has a pair of spaced ears 42, 42 thereon through which a rod 43 isslidab-ly mounted and which is adapted to impart a. rocking movement tothe plate 39 and through the link 31, thereby opening and ciosing thevalve 36, admitting fuel to the burner 25a when it is desired to operatethis burner.

In the operative position of the stove, the rod 43 extends through aslotted opening in the end of the housing ii) so that an up and downmovement of the rod 43 imparts a rocking action to the plate 39 forpurposes of opening and closing the valve as heretofore described. Inthe disassembled or packed position of the stove, this rod is movedinward, as shown particularly in Figure 4, so that the whole burnerassembly can be packed inside of the housing I0.

In operation, the stove is normally in its packed position as shown inFigure 4, wherein the burner assembly and fuel tank are placed in sideposition on the bottom of the housing Hi, with the rod 43 pushed inwardinside of the housing, the lid H being closed, in which condition thestove can be transported from place to place as desired. One of the gridmembers has a projecting rod 44 which projects down over the manifold 23and serves to hold the stove assembly from movement when in its packedposition in the housing Hi. When it is desired to assemble the stove foroperation, the lid and grid are raised upward, the assembly is removedfrom the housing 19, the burner assembly pushed into the housing 10through the opening l2, the track l1 being in engagement with the track15 until a U-shaped stop member 45, mounted on the under side of themixing tube 25, engages with the stop 16 and prevents further inwardmovement of the burner assembly and also prevents the burner assemblyfrom tilting or rocking in the track l5. The legs M, in the meantime,have been withdrawn to support the housing if! a sufiicient distancefrom the ground to enable the fuel tank [8 to be placed under thehousing if The rod 43 is moved outward so that the end thereof projectsbeyond the housing iii, the grid I3 is placed over the burners, in whichposition the stove is in condition for operation, the fuel beingsupplied through the valves as described in my Patent No. 1,914,393.

In case it is desired to use the burner 260, the rod 43 is liftedupwardly, opening the valve 35, thereby admitting the fuel mixture intothe burner-25a which is lighted. By proper adjustment of the rod 43 thevalve 36 can be opened the proper degree to control the height of theflame in the burner 2611, with the spring 4| exerting sufficientpressure against the side of the plate to hold this valve in itspredetermined adjusted position.

It will be understood, of course, that a liquid fuel such as gasoline orthe like, is supplied to the tank and by means of proper pumparrangement, as heretofore described, air under pressure is placed inthe tank l8, which forces the fuel through the valve assembly, throughthe generator tube 28 into the manifold 23.

In disassembling the burner arrangement, it is only necessary to pulloutward 0n the burner assembly, with the track I! sliding along thetrack l5 until the assembly is removed from the housing, when the rod 43is pushed inward and the whole structure placed inside of the housing iiThe legs are pushed inward and the lid and grid closed, making a compactpackage which can be easily transported and handled as desired.

While I have described more or less precisely the details ofconstruction, I do not wish to be understood as limiting myself thereto,as I contemplate changes in form and the proportion of parts and thesubstitution of equivalents as cirstances may suggest or renderexpedient without departing from the spirit or scope of my invention.
